2000 honda accord v6 3.0
Was getting codes 300, 304, 305, 1399 took it to to
mechanic and he said he put machine on it and it
was the thermostat and a sensor. Two days after
the engine light came on again..yesterday they
changed the spark plugs, the intake gaskets and
now these codes are coming up 300 304 305 and
and a noise like a whining noise when I drive you
can't really hear it but when you stop you can hear
it. It comes and goes.
